Current marsh pollution has dramatic, negative effects on sea anemone’s survival
Stationary marine organisms that don’t ply the ocean, but spend their lives rooted in one spot, have evolved impressive ways to capture prey. The sea anemone Nematostella, for instance, burrows into salt marsh sediments and stays there for life. But it has specialized ‘stinging cells’ that hurl toxins into passing prey, immobilizing the morsel so […]
Birds’ dazzling iridescence tied to nanoscale tweak of feather structure
The iridescent shimmer that makes birds such as peacocks and hummingbirds so striking is rooted in a natural nanostructure so complex that people are only just beginning to replicate it technologically. The secret to how birds produce these brilliant colors lies in a key feature of the feather’s nanoscale design, according to a study led […]
